The Great Lakes Commission, authorized by the region's American states and Province of Ontario, and the additional Canadian Province of Quebec, comprises a bi-national authority with specified powers to protect and preserve the water and environmental resources of the Great Lakes and surrounding waterways and aquifers. The Commission's authorities are confirmed by the Canadian and American federal governments, and by its constituent states and provinces. The states and provinces are represented in the Conference of Great Lakes and St. Lawrence Governors and Premiers.

The Great Lakes region, as distinct from the Great Lakes Basin, defines a unit of sub-national political entities defined by the U.S. states and the Canadian Province of Ontario encompassing the Great Lakes watershed, and the states and Province bordering one or more of the Great Lakes.

History

Prior to European settlement, Iroquoian people lived around Lakes Erie and Ontario, Algonquian peoples around most of the rest, and a variety of other indigenous nation-peoples including the Menominee, Ojibwa, Illinois, Pottawatmie, Huron, Shawnee, Erie, Fox, Miami, Meskwaki and Ho-Chunk (Winnebago). With the first permanent European settlements in the early seventeenth century, all these nation-peoples developed an extensive fur trade with French, Dutch, and English merchants in the St. Lawrence, Hudson and Mohawk Valleys, and Hudson's Bay, respectively.

The prospects of fur monopolies and discovery of a fabled Northwest Passage to Asia generated sporadic but intense competition among the three most powerful northwest Europe imperial nations to control the territory. A century and a half of naval and land wars among France, The Netherlands and Britain resulted finally in British control of the region, from the Ohio River to the Arctic, and from the Atlantic to the Mississippi. Beyond the region, North American claims remained disputed among Britain, France, Spain and Russia.

During the American Revolution, the region was contested between Britain and rebellious American colonies. Hoping for favorable claims of territorial control in an eventual peace treaty with Britain, American adventurers led by Kentucky militia leader George Rogers Clark briefly occupied village settlements, including Cahokia, Kaskaskia and Vincennes unopposed, with passive support from Francophone inhabitants. In the Peace of Paris (1784) Britain ceded what became known as The Northwest Territory, the area bounded by Great Lakes, Mississippi and Ohio rivers, and the eastern colonies of New York and Pennsylvania, to the fledgling United States. Britain, which may have entertained ambitions to repossess the area if America failed to govern it, retained control over its forts and licensed fur trade for fifteen years.

During the Confederacy Period of 1781–1789, the Continental Congress passed three ordinances whose authority was unclear regarding the region's governance on the American side. The Land Ordinance of 1784 established the broad outlines of future governance. The territory would be divided into six states, which would be given broad powers of constitutional instituting, and admitted to the nation as equal members. The Land Ordinance of 1785 specified the manner in which land would be distributed in the Territory, favoring sale in small parcels to settlers who would work their own farms.

The Northwest Ordinance of 1787 defined the political protocols by which American states south of the lakes would enter the union as political equals with the original thirteen colonies. The ordinance, adopted in its final form just before the writing of the United States Constitution, was a sweeping, visionary proposal to create what was at the time a radical experiment in democratic governance and economy. The Northwest Ordinance of 1787 prohibited slavery, restricted primogeniture, mandated universal public education, provided for affordable farm land to people who settled and improved it, and required peaceful, lawful treatment of the Indian population. The ordinance prohibited the establishment of state religion and established civic rights that foreshadowed the United States Bill of Rights. Civil rights included freedom from cruel and unusual punishment, trial by jury, and exemption from unreasonable search and seizure. States were authorized to organize constitutional conventions and petition for admission as states equal to the original thirteen. Five states evolved from its provisions: Ohio, Indiana, Michigan, Illinois, and Wisconsin. The northeastern section of Minnesota, from the Mississippi to St. Croix River, also fell under ordinance jurisdiction and extended the constitution and culture of the Old Northwest to the Dakotas. The surge of settlement generated tension culminating in the Battle of Fallen Timbers in 1794.

Britain, fearing that fast American settlement could lead to annexation of its western provinces, countered with The Constitution Act of 1791, granting limited self-government to Canadian provinces, and creating two new provinces out of Canada: Lower Canada (today's Quebec) and Upper Canada (Ontario).

Settlement and economic expansion on both sides accelerated after the 1825 opening of The Erie Canal, an astonishingly successful public venture that effectively integrated markets and commerce between the Atlantic seaboard and the region. The region on both sides of the border became a vast research and design laboratory for agricultural machinery and techniques. Owner-operator family farms transformed both demographics and ecology into a vast terrain of farmlands, producing primarily wheat and corn. In western New York and northeast Ohio, the St. Lawrence, Mohawk, and Hudson rivers provided outlets for commercial corn and wheat, while The Ohio River let agricultural products from western Pennsylvania and southern Ohio, Indiana and Illinois journey downstream to New Orleans. Mining, primarily soft metals of copper, zinc, and lead; and timber to supply rapidly expanding sawmills that supplied lumber for new settlements.

Agricultural and industrial production generated distinctive political and social cultures of independent republican producers, who consolidated an ideology of personal liberty, free markets, and great social visions, often expressed in religious terms and enthusiasms. The region's alliance of antislavery with free soil movements contributed troops and agricultural goods that proved critical in the Union's victory. The Homestead and Morrill Acts, donating federal land to extend the agrarian economic franchise, and support state universities, modeled western expansion and education for all future states.

The British-Canadian London Conference of 1866, and subsequent Constitution Act of 1867 analogously derived from political, and some military, turmoil in the former jurisdiction of Upper Canada, which was renamed and organized in the new dominion as the Province of Ontario. Like the provisions of the ordinance, Ontario prohibited slavery, made provisions for land distribution to farmers who owned their own land, and mandated universal public education.

Industrial production, organization, and technology have made the region among the world's most productive manufacturing centers. Nineteenth-century proto-monopolies such as International Harvester, Standard Oil, and United States Steel established the pattern of American centralized industrial consolidation and eventual global dominance. The region hosted the world's greatest concentrations of production for oil, coal, steel, automobiles, synthetic rubber, agricultural machinery, and heavy transport equipment. Agronomy industrialized as well, in meat processing, packaged cereal products, and processed dairy products. In response to disruptions and imbalances of power resulting from so vast a concentration of economic power, industrial workers organized the Congress of Industrial Organizations, a coherent agricultural cooperative movement, and the Progressive politics led by Wisconsin's Governor and Senator Robert M. La Follette Sr.. State universities, professional social work, and unemployment and workers' compensation were some of the region's permanent contributions to American social policy.

Chicago and Detroit carry important roles in the field of architecture. Chicago pioneered the world's first skyscraper, the Home Insurance Building designed by William LeBaron Jenney. Engineering innovation established Chicago from that time on to become one of the world's most influential epicenters of contemporary urban and commercial architecture. Equally influential was the 1832 invention of balloon-framing in Chicago which replaced heavy timber construction requiring massive beams and great woodworking skill with pre-cut timber. This new lumber could be nailed together by farmers and settlers who used it to build homes and barns throughout the western prairies and plains. Wisconsin-born, Chicago-trained Sullivan apprentice Frank Lloyd Wright designed prototypes for architectural designs from the commercial skylight atrium to suburban ranch house.

German-born Pennsylvania immigrant John A. Roebling invented steel wire rope, a pivotal part of suspension bridges he designed and whose construction he supervised in Pittsburgh, Cincinnati and Buffalo, based on earlier successful canal aqueducts. His most famous project was the Brooklyn Bridge.

Contributions to modern transportation include the Wright brothers' early airplanes, designed and perfected in their Dayton, Ohio mechanics' workshops; distinctive Great Lakes freighters, and railroad beds constructed of wooden ties and steel rails. The early nineteenth century Erie Canal and mid-twentieth century St. Lawrence Seaway expanded the scale and capacity of massive water-born freight.

Agricultural associations joined the nineteenth century Grange, which in turn generated the agricultural cooperatives that defined much of rural political economy and culture throughout the region. Fraternal, ethnic, and civic organizations extended cooperatives and supported local ventures from insurance companies to orphanages and hospitals. The region was the political base, and provided much leadership political parties in the region.

The region's greatest institutional contributions were major corporate, labor, educational and cooperative organizations. It hosted some of the most influential national and international corporations of the late nineteenth and early twentieth century monopoly age, including John Deere Plow, McCormack Reaper, New York Central and Erie railroads, Carnegie Steel, U.S. Steel, International Harvester and Standard Oil. In part to balance democratic representation against the economic and political power of these corporations, the region hosted industrial labor organization, consolidated agricultural cooperatives and state educational systems. The Big Ten Conference memorializes the nation's first region in which every state sponsored major research, technical-agricultural, and teacher-training colleges and universities. The Congress of Industrial Organizations grew out of the region's coal and iron mines; steel, automobile and rubber industries; and breakthrough strikes and contracts of Ohio, Indiana, and Michigan.

During World War II, the region became the global epicenter of motorized land vehicles, including cars, trucks and jeeps, as well as a major supplier of engine, transmission, and electrical components to the wartime aeronautics industry. Despite extreme labor shortages, the region increased mechanization, and absorbed large numbers of women and immigrant labor, to increase its food production.

Navigable terrain, waterways, and ports spurred an unprecedented construction of transportation infrastructure throughout the region. The region is a global leader in advanced manufacturing and research and development, with significant innovations in both production processes and business organization. John D. Rockefeller's Standard Oil set precedents for centralized pricing, uniform distribution, and controlled product standards through Standard Oil, which started as a consolidated refinery in Cleveland. Cyrus McCormick's Reaper and other manufacturers of agricultural machinery consolidated into International Harvester in Chicago. Andrew Carnegie's steel production integrated large-scale open-hearth and Bessemer processes into the world's most efficient and profitable mills. The largest, most comprehensive monopoly in the world, United States Steel, consolidated steel production throughout the region. Many of the world's largest employers began in the Great Lakes region.

Mass marketing in the modern sense was born in the region. Two competing Chicago retailers—Montgomery Ward and Sears Roebuck—developed mass marketing and sales through catalogues, mail-order distribution, and the establishment of their brand names as purveyors of consumer goods. The region's natural features, cultural institutions, and resorts make it a popular destination for tourism.

Advantages of accessible waterways, highly developed transportation infrastructure, finance, and a prosperous market base make the region the global leader in automobile production and a global business location. Henry Ford's movable assembly line and integrated production set the model and standard for major car manufactures. The Detroit area emerged as the world's automotive center, with facilities throughout the region. Akron, Ohio became the global leader in rubber production, driven by the demand for tires. Over 200 million tons of cargo are shipped annually through the Great Lakes.[2][3][4]

According to the Brookings Institution, if it stood alone as a country, the Great Lakes economy would be one of the largest economic units on Earth (with a $4.5-trillion gross regional product). This region also contains what area urban planners call the Great Lakes Megalopolis, which has an estimated 59 million people. Chicago is emerging as the third megacity in the United States, after the New York City and Los Angeles metropolitan areas, with a metro population approaching ten million. Cities along the Great Lakes have access to the Atlantic Ocean through the St. Lawrence Seaway, making them international ports.

Geography

The Palaeozoic strata, are but parts of a great area of similar strata hundreds of feet in thickness. These strata decline gently southward from the great upland of the Laurentian Highlands of eastern Canada. The visible upland area of today was but a small part of the primeval continent with the remainder of it still buried under a Palaeozoic cover. The visible part was the last part of the primeval continent to sink under the advancing Palaeozoic seas. When the upland and its overlap of stratified deposits were elevated again, the overlapping strata must have had the appearance of a coastal plain. Of course that was long ago; since then the strata have eroded substantially and today possess neither the area nor the smooth form of their initial extent. This district may be considered an ancient coastal plain. As is always the case in the broad denudation of the gently inclined strata of such plains, the weaker layers are worn down in sub-parallel belts of lower land between the upland and the belts of more resistant strata, which rise in uplands.

Niagara Escarpment (in red)

Few better illustrations of this type of forms are to be found than that presented in the district of the Great Lakes. The chief upland belt or escarpment is formed by the firm Niagara limestone/dolostone, which takes its name from the gorge and falls cut through the upland by the Niagara River. As in all such forms, the Niagara Escarpment has a relatively strong slope or infacing escarpment on the side towards the upland, and a long gentle slope on the other side. Its relief is seldom more than 200 or 300 feet (91 m) and is generally small. Its continuity and its contrast with the associated lowlands on the underlying and overlying weak strata suffice to make it an important feature. The escarpment would lie straight east-west if the slant of the strata were uniformly to the south. However, the strata are somewhat warped and so the escarpment's course is strongly convex to the north in
the middle, gently convex to the south at either end.

The arrangement of the Great Lakes closely matches the course of the lowlands worn on the two belts of weaker strata on either side of the Niagara escarpment. Lake Ontario, Georgian Bay and Green Bay occupy depressions in the lowland on the inner side of the escarpment. Lake Erie, Lake Huron and Lake Michigan lie in depressions in the lowland on the outer side. When the two lowlands are traced eastward, they become confluent after the Niagara limestone has faded away in central New York, and the single lowland is continued under the name of the Mohawk Valley. This is an east-west longitudinal depression that has been eroded on a belt of relatively weak strata between the resistant crystalline rocks of the Adirondacks on the north and the northern escarpment of the Appalachian plateau (Catskills-Helderbergs) on the south. Early in U.S. history, this provided a vital economic route between the Atlantic seaports and the U.S. interior.

In Wisconsin, the inner lowland has an interesting feature. It is a knob of resistant quartzites, known as Baraboo Ridge, rising from the buried upland floor through the partly denuded cover of lower Palaeozoic strata. This knob or ridge can be thought of as an ancient physiographic fossil, as it is an ancient monadnock having been preserved from destructive attacks of weather by burial under sea-floor deposits. It has been recently re-exposed through the erosion of its cover.

The occurrence of the lake basins in the lowland belts on either side of the Niagara escarpment is an abnormal feature. Ordinary erosion does not explain it. Glacial erosion has formed them through the glacial drift obstructing the normal outlet valleys and to crustal warping in connection with or independent of the glacial sheet.

Lake Superior is unlike the other lakes. The greater part of its basin occupies a depression in the upland area, independent of the overlap of Palaeozoic strata. The western half of the basin occupies a trough of synclinal structure. The Great Lakes are peculiar in receiving the drainage of but a small peripheral land area, enclosed by an ill-defined water-parting from the rivers that run to Hudson Bay or the Gulf of Saint Lawrence on the north and to the Gulf of Mexico on the south.

The three lakes of the middle group stand at practically the same level:

Lake Michigan

Lake Huron

Lake Erie

Lake Michigan and Lake Huron are connected by the Straits of Mackinac with the Mackinac Bridge spanning the straits. Lake Huron and Lake Erie are connected by the St. Clair River and Detroit River, with the small Lake St. Clair between them. The land northeast of the rivers is undergoing a slow elevation. The Niagara River connecting Lake Erie and Lake Ontario, with a fall of 326 feet (99 m) (160 feet (49 m) at the cataract) in 30 miles (48 km), is of very recent origin, as an older river would have a mature valley. The original valley that is thought to have connected the two depressions through the Niagara Escarpment is thought to have been at the present route of the Welland Canal, and to have been completely filled with glacial drift. The same is true for the St. Lawrence, where there may not have been an original valley. The Ontarian River that was a precursor to Lake Ontario is thought to have drained westward, and the St. Lawrence drainage to have been created by subsidence due to the weight of the ice sheet.
